Setting a benchmark for performance, the LM4562 audio op amp specifies a THD+N figure of 0.00003%. The device combines a 6-MHz, unity-gain bandwidth operational amplifier with a proprietary ...

A critical measure for all audio components is distortion, typically specified as total harmonic distortion (THD) or total harmonic distortion + noise (THD+N). THD is defined as: ... THD+N is the rms ...

Class-D audio amplifiers are power efficient, but do not beat, or even match, well-designed Class-AB and Class-A amplifiers on many other specs. This said, Delft University of Technology, working with ...

International Solid-State Circuits Conference in San Francisco always seems to make space for audio amplifier developments, and this year is no exception, with some extraordinary distortion and noise ...

Fundamental analog devices that serve applications such as high-resolution delta-sigma or SAR (successive-approximation-register) converter systems are feeling the crunch from amplifiers that have ...
